Federal Aviation Administration (FAA), Department of Transportation (DOT).
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600); and Model A310 series airplanes; equipped with certain Honeywell inertial reference units (IRUs). This AD requires revising the Limitations section of the airplane flight manual to prohibit the use of CAT 2 and CAT 3 automatic landing and rollout procedures at certain airports. This AD is prompted by a report that some magnetic deviation tables in the IRU database are obsolete and contain significant differences with the real magnetic deviations. We are issuing this AD to prevent an airplane from deviating from the runway centerline, and possibly departing the runway.
This AD becomes effective April 15, 2005.
The incorporation by reference of certain publications listed in the AD is approved by the Director of the Federal Register as of April 15, 2005.
For service information identified in this AD, contact Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France.
Docket: The AD docket contains the proposed AD, comments, and any final disposition. You can examine the AD docket on the Internet at http://dms.dot.gov, or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227) is located on the plaza level of the Nassif Building at the U.S. Department of Transportation, 400 Seventh Street, SW., room PL-401, Washington, DC.

The FAA proposed to amend 14 CFR part 39 with an AD for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600); and Model A310 series airplanes; equipped with certain Honeywell inertial reference units (IRUs). That action, published in the Federal Register on November 5, 2004 (69 FR 64520), proposed to require revising the Limitations section of the airplane flight manual (AFM) to prohibit the use of CAT 2 and CAT 3 automatic landing and rollout procedures at certain airports.
We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been submitted on the proposed AD. The commenter supports the proposed AD.
Explanation of Changes Made to This Final Rule
We have revised Table 2 of this AD to more clearly identify the applicable airplane flight manuals (AFM) to be revised.
In Table 2 of the proposed AD we referenced an incorrect date for the temporary revisions. We have revised Table 2 of this final rule to correct that information.
We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD as proposed, with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD will affect about 136 airplanes of U.S. registry. The AFM revision will take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, Start Printed Page 12118the estimated cost of the AD for U.S. operators is $8,840, or $65 per airplane.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a “significant regulatory action” under Executive Order 12866;
(2) Is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this AD. See the ADDRESSES section for a location to examine the regulatory evaluation.Start List of Subjects
